Liz Cheney, the daughter of former VP Dick Cheney - who, in an interview with ABC News' John Karl, called the selection of Sarah Palin in 2008 "a mistake" - disagreed with her father on Twitter a short while ago:

Rarely do I disagree with best VP ever but @SarahPalinUSA more qualified than Obama and Biden combined. Huge respect 4 all she's done 4 GOP.

Liz Cheney has emerged as a player in conservative national security circles, and is also rumored, as Jonathan Martin put it, to be considering a political run of her own in the future. Palin is nowhere near the relevant force she was even two years ago, but she still has a following.
